Negative-Stiffness Vibration Isolation Gains Popularity

By Dr. David L. Platus, Minus K Technology Inc. and Jim McMahon, Zebra Communications.


Negative-stiffness mechanism vibration isolation enables laser/optical instruments such as SPMs, microhardness testers and optical profilers to operate in severe vibration environments that would not be practical with other passive and electronic isolation systems. Laser and optical systems, whether used in academic labs or industry, are very susceptible to vibrations from the environment, so these instruments frequently need vibration isolation. When measuring a very few angstroms or nanometers of displacement, an absolutely stable surface has to be maintained upon which to rest the...Read full article

    ellipsometry
    The measurement of the change in ellipticity of an optically polarized light beam after reflection from a surface in a particular manner.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
